The process of upwelling is caused by the interaction of which two spheres
hydrosphere and atmosphere

Nick lives in Houston, Texas in the southern part of the US. The usual amount of rainfall is 50 inches per year with an average of 160 days of rain while winter temperatures are in the mid 40s in degrees Fahrenheit summer temperatures are generally in the 90s in degrees Fahrenheit. What do these statistics describe?
Climate

Sophia had a world map and she looked at Greenland and she studied the map. She noticed that the Arctic Circle runs through the southern tip of Greenland in what climate zone is Greenland and what sort of features would it have?
Polar with ice caps

In one of the exhibits, he saw a fossilized warm weather plant that had been found in Antarctica. He was surprised, but he knows that scientist use a variety of ways to study past climates. Why would a warm weather plant fossil be found in Antarctica? choose the two that apply.
earths continents move gradually Antarctica climate was warmer in the past
68
Brody knew that earth climate could be unpredictable. However he was surprised to learn that a warming climate would bring some serious changes and that organisms would have to adapt or die out what conditions might result from warming temperatures.
New environmental conditions Changing weather patterns

In polar regions, a thin layer of soil supports plant life the soil below this layer called permafrost is frozen year-round. How could melting permafrost accelerate global warming?
Additional carbon dioxide would enter the atmosphere as decomposing plant matter is exposed

Clara’s grandfather is the captain of a cargo ship. He prefers to navigate his ship through the moderate neap tides at these times the line between earth and the sun is at a right angle to the line between earth and the moon, which phase or phases of the moon describe this alignment.
First and third quarter
71
Different alignments of the earth and moon and sun can cause phenomena to ink occur on earth. These phenomena are caused by differences in gravitational pulls. What are these phenomena?
Tides
72
Why does earth have seasons?
Because earths access is tilted as it revolves around the sun
73
Stefan learned that there are two forces that keep the moon in orbit around earth. How do these forces keep the moon from flying off into space
Gravity attracts the moon toward earth and inertia keeps the moon in motion

Hassam is making a model showing the interior of the sun. He discovers the interior of the sun consist of gases layers that produce and distribute heat energy in which layer of the sun is most of the heat in form of electromagnetic radiation.
Radiative zone
75
On April 5, 1991 a space telescope was launched for the space shuttle at Atlantis. This observatory used for primary instruments to locate an observe high energy radiation in space radio waves have the longest wavelengths and lowest energy on the electromagnetic spectrum. The high energy radiation being observed by the space telescope has a shortest wavelength. What is it called?
gamma rays
76
With technological advances such as the JWST Astronomers can study distant stars. These stars can be compared to our son to better understand them, which feature of the sun do astronomers used to observe the sun rotation.
Sunspots
77
Astronomers can observe many stars being formed in the Orion nebula gravity starts to form the beginnings of a star by pulling in gas and dust from the surrounding cloud what is this first stage of a star called
Protostar
78
Ethan visited the Crosby observatory at the Orlando science center the observatory houses the largest refracting telescope available to the public in Florida one night he observes several stars that all seem to be equally bright however, one of the astronomers explained that each star actually had a different absolute brightness. What information do you need to calculate? A star absolute brightness choose the two that apply.
Distance from earth Color and temperature
79
People are fascinated with the possibility of life on other planets when looking for signs of life on other planets, scientist often look for planets that have similarities to earth according to the chart which planet has a rotation most similar to earths
Mars

Alex was confused about what happens when massive stars die line explains that sometimes after a star dies the gravity of the remaining mass can be so strong that it pulls the gas is inward packing it into a smaller and smaller space. What is this called? A black hole.
Black hole
